l APPARATUS FOR TAPING RoxEs.

Application filed April 29, 1927. Serial No. 187,672. i i

This invention relates `to a novelv and iinproved apparatus for taping boxes and contapingl apparatus.

ed claims. l l

In an application heretofore filed by me on May 18, 1923, Serial No. 639,727', Ihave de scribed a fibre or paper board box consisting of a tubular body and of a head or heads closy,

ing the body, with each head secured to the body by means of gummed tape wound in a succession of windings about the box and with part of its width secured to the bodj,1 and the other part to the head, thereby rigidly connecting the head and body together.

The object of thev present invention is to provide an apparatus by `means of wliichthe tape used for securing the head to the body of such aA box maybe rapidly and quickly applied in the manner described. lThe advantages of the invention will appear more fully as l proceed with` my specification.

Referringnow to that embodiment of the inventionv illustrated in the drawings:-10 indicates a table 'having a topV lland legs 12. This table may be of any suitableconstruo tion and is so constituted as to provide a rigid structure. 13 indicates a rotary table or platform mounted on the table top 11. Said platform is fixed on a flanged spindle 14 which is rotatably mounted in a vertical p fianged'sleeve 15 disposed in a suitable openingin the table top 11 as shown. The flange 16 ofthe spindle provides a base for the plantform 13 and the flange 17 of the sleeve provides supporting engagement for the sleeve artnr oFFicE.

with the table top 11. A collar 1.7X on the 'y spindle 14 is interposed'between the top end of the sleeve 15 and the spindle flange 16to provide a bearingbet'ween the two.

18 indicates a form to receive the body of thebox when the first or'bottom head is applied thereto. This form is preferably an ordinary wooden box which has the size and form of the inner dimensions of the fibre board box, the head of which is to'be applied. There may be provided in connection with the apparatus, one or more of such forms 18 as desired to accommodate boxes of different sizes. The bottomf19 of this form has a cen. tering pin 20 adapted for engagement in a hole or opening in the platform 13 and the top'21 of the box preferably has a hand hole 22 for convenience in lifting the form and re moving it from the table.

i On the platform are mounted a pluralityvl of brackets 23 which have slotted bases bolted to the platform 13 as illustrated. Said brackets present upright shoulders lfor engage'- ment with the several upright faces of the box and are capable of adjustment to accom-` modate boxes kof different cross sectional area.

At one side of the table is fixed an upright frame 24 of any suitable construction, preferyably made of angle bars.` On said frame above the table isa horizontal spindle 25 adapted to receive a roll of tape 26. The frame 24 has a comparatively long yhorizontal arm 27 extending beyond the table and* at the end of which is kmounted a box 28 to contain water. 29., and 31 indicate horizonktal idle rolls carried by the arm 27 and by the Vbox 28 .about which rolls the strip of ytape 26 is led from the roll of tape 26. The roll 31 is mounted. on the water box 2S with its bottom side submerged in the water contained there-- in. Said roll picks up the water and applies it to the gummed side of the tape as said tape passes over it, in a familiar manner. Froml i which is not gummed. pressed finger 33 (see Figures lY and 3) y1eld-V ingly holds the tape against'the roll 32, and prevents the severed end from dropping after a'box has been taped. vertically adjustable by set screw 32h, holds thebottom edge of the tape in the desired horizontal plane and prevents it from run- 1 ning belowr that plane as the tape is fed towards the box'. Y

vAdjacent the roll 82 is located a shearing device 34. This consists of a fixed member 35 and of a member 36 hinged thereto and adapted to coact therewith to cut the tape.l A vertical connecting rod 37 1s pivotally con nected to a heel 36 of the hinged member 86 and is carried down to the bottom of the table fwhere it is connected to a rock arm 38 on a rock shaft 39, 'adapted to be actuated by a ltrea-dle 40. A coiled spring 4l, connecting lthe rod 37 to a lug on the fixed shear member 35, normallyholds the movable shear member 36 out of the way and in inoperative relation. Manifestly a pressure on the treadle 40 will swing said hinged member 36 in such manner as to cut the tape against the fixed shear member 85', as will be apparent from examination of Figure 2.

The connecting rod 37 is preferably com-Y prised of two parts 87.,- 37 b1 adjustably connected together by a block and set' screw 37.

K rlhe frame 24 is also made vertically adjustable on the table l0 as by the bolt 24X and slot 24y (see Figure 3.,), so as to accommodate boxes of different body lengths.

In Figure 41s shown an implement or tool `45 for laying the tape simultaneously on the head and on the body of the box. Said tool consists of a roller 46 on shaft 47 mounted in the tines 48 of a fork 49. 50 indicatesA a handle fixed lto the fork 49. The roller 46 is made up of truncated cones 46a, 46a fixed together with their truncated heads abbutting,

their conical axes in alignment and common y to the axis of the .shaft 47 and with their conical surfaces diverging at a right angle.'V The construction is thus that when the tool is ap plied to the edge of the box as shown in Figure 2, one cone 46a will closely engage the A beveled collar 32? side of the box, while the other will closely engage the top of the box. The parts of the tool are made of such strength that considerable pressure may be exerted by it against the parts of the box engaged7 and the surfaces of the cones are preferably coated with rubber or like yielding material.

The apparatus is operated as follows.: n

A suitable form 18 is selected to receive the tubular body A (see Figure 5) which is to be headed. Said form is placed Von the platform-13 with its centering pin 2O properly locating it on the platform. The tubular bodyA is then slipped over the form as shown in Figure 6 and its bottom end` is brought down tobear on the platform 18. This leaves the top edges of the tubular body projecting somewhat above thel top of the form, as shown at a in Figure 6, an amount equal to the thickness of the head to be applied to the tubular body. A head B for that box is then placed on the top of the formand engaged within the top end of the tubular body A. The head will now lie with its outer face'flush with the top edges of the tubular body A, as

Vshown Figure 7 vThe frame 24 (and also the connecting rod 37) are then adjusted to bring the verticalpart of the tape 26a when it passes about the vertical wall 32 into a position where part ofits Width, preferably one` 'half its width, extends-below the level of the plane of the top face of the head B and the other part of its width extends above' that plane. Thel tape is then drawn forward along one side of the box and the end part is by hand adhered'to the side of the box body near the top. The part of the width'off the tape extending above the box is likewise adhered by hand to the top of the box. i

rlhe tool 45 for laying the tape is then applied with the surfaces of its two truncated cones engaged, one with the part ofthe tape on the box body and the other on" the part of the tape on thel head. The toolinthis position is then run along the corner at the head ofthe box laying the tape and adheringl it part to the head and part to the box body. When Vone end of the side ofthe head is reached the box is turned with the table which supports it, the tape being wound. in the turning movement upon the next following` side of the box.y Themovenient of the tool is continued along that side laying the tape as before on the side and top of the box; the box is given another turn and the operation is continued. At the angle where4 two sides meet the tool efficiently folds down the tape on the head to form a lap. Sufficient Apresw sure is used in applying the tool to securely adhere the tape'both to the box body and to the head. In this manner the tape is applied in a plurality of windings, as shown in Figure ll, and as many windings are applied as may be needed in order to efficiently secure the for which it is intended. After as many windings have been applied as are intended, the shearing device 34 is actuated by the treadle 40 to sever the tape, the end of which is properly adhered to the head and body.

After the one head has been thus applied,the box is turned about with its'other open end up and the head already applied in position on a suitable support as the bottom of the box. The box is then packed. In packing, the contents are brought only to a level below the open end of the tubular body which will allow the thickness of the other head to remain unfilled by the contents. then placed with the open end up on the rotary table or platform 18 (the form 18 having in the meantime been removed) and the brackets 23 are adjusted to bear against the upright faces of the box body iii order to hold the box securely in position on the platform. The second head is now applied and the tape wound thereon and applied to the head and body in a plurality of windings as before. This finishes the operation,the box being now ready for shipping.
